The study population was made up of active-duty US Army, Navy, and Marines personnel who have at least one blood sample in the Department of Defense Serum Repository. The electronic databases of the Physical Disability Agencies of the US Army and Navy were then searched for individuals whose records indicated a possible diagnosis of MS reported between 1992 and 2004.
The researchers selected 305 individuals diagnosed with MS and who had blood specimens collected before the date of their diagnosis. Two controls for each case were then selected from the serum database and matched by branch of service, sex, date of blood collection, and age at time of blood collection.
The study found that MS risk is extremely low among individuals not infected with EBV, but it increases sharply in the same individuals following EBV infection.
"The observation that MS occurred only after EBV is a big step forward," said Alberto Ascherio. "Until now we knew that virtually all MS patients are infected with EBV, but we could not exclude two non-causal explanations for this finding: that EBV infection is a consequence rather than a cause of MS, and that individuals who are EBV negative could be genetically resistant to MS. Both of these explanations are inconsistent with the present findings," said Ascherio.
"The evidence is now sufficiently compelling to justify the allocation of more resources to the development of interventions targeting EBV infection, or the immune response to EBV infection, as these may contribute to MS prevention," he said.
